WEATHERBY. — MEXICAN PHANEROGAMS. 423 



cescens duplo brevioribus. — Guerrero: between Ayusiriapa and 

 Petatlan altitude 1500-2000 m., Dec. 14, 1894, Nelson, no. 2120 (in 

 hb. U. S. Nat. Mus.). Near A. leptophjllum Baker, from which it 

 differs in its even more slender babit, narrower. and longer leaves, 

 and several -bracted stem. Very similar also to Echeandia Pringlei 

 Greenman, but witb free anthers. 



Anthericum uncinatum, n. sp., scaposum, radicibus medio in- 

 crassatis, collo radicis dense fibroso, foliis (6-7) 8-12 cm. longis 

 6-10 mm. latis pallide viridibus saepius patentibus valdeque fal- 

 catis in siccis conduplicatis membranaceis marginibus manifestis albis 

 cartilagineis ciliolatis lente nervatis, caulibus circa 3 dm. altis simplici- 

 bus scabris vel hirtellis 1-2-bracteatis bracteis setaceo-acuminatis 

 chartaceis, pedicellis floriferis 5-7 mm. longis infra medium articu- 

 latis, perianthii fiavi (?) segmentis 8-12 mm. longis, filamentis papil- 

 loso-crispatis circa 5 mm. longis antheris longioribus, capsulis immatu- 

 ris brevibus ovoideis. — Durango : Otinapa, July 25-Aug. 5, 1906, 

 Palmer, no. 437. Near A. scabrellum Baker, from wbich it differs in 

 its cartilaginous-margined and strongly falcate leaves; similar to those 

 of A. drepanoides Greenman. From the latter species it differs in 

 its scabrous stem, smaller size, and fewer, chartaceous bracts. In A. 

 drepanoides the bracts are about 5, and the lower are foliaceous and 

 falcate, like the root-leaves. 



Nemastylis (§ Chlamydostylus) latifolia, n. sp., bulbo ovoideo 

 tunicis brunneis friabilibus, caule simplici subflexuoso in speciminibus 

 visis circa 4.5 dm. alto folium unicum erectum bracteamque vaginan- 

 tem gerente, folio radicali uno lineari -lanceolate longe acuminate apice 

 setaceo 3 dm. longo 1-1.5 cm. lato plicato valde nervato, folio caulino 

 simili inflorescentia breviore vel earn aequante ejus vagina 3-3.5 cm. 

 longa scariosi-marginata, bractea acuminata scariosi-marginata 7.5-8.5 

 cm. longa, spatha 5.3 cm. longa valvis acuminatis aequilongis vel ex- 

 teriore paulum longiore, fioribus in spatha 4, pedicellis filiformibus 

 spatham aequantibus vel exsertis, perianthiis albis marcescentibus 

 paulum caerulescentibus 3 cm. (?) latis, filamentis brevissimis minus 

 quam 1 mm. longis, antheris 1 cm. longis connectivis angustis, styli 

 ramis filiformibus antheras subaequantibus parte indivisa circa 1 mm. 

 longa, fructu non viso. — Guerrero: hills, near Iguala, alt. 915 m., 

 July 29, 1907, Pringle, no. 10,391. Distinguished from all the other 

 Mexican species hitherto described by its very short, almost obsolete 

 filaments. In this respect it resembles some of the South American 

 species, but is not satisfactorily referable to any of them. 



Quercus (§ Erythrobalanus) rysophylla, n. sp., arborea magna, 

 cortice nigricante aspera vel profunde sulcata, foliis integris ovato-
